- player_score>=computer_scoremakes the computer win even when they score the same. A comparison should be- >instead of `>='- >=(same for the next clause).
- The game, as coded, may terminate early (before reaching 5 rounds). For me, it contradictcontradicts the requirements. 
- User input shall be validated (is it really a number?) somehow. 
- I don't know if you covered functions already. If so, factor out all the copy-pastes into functions.
